7NC22 Charcoal Adsorber Canister

Products Description

 

The 7NC22 Charcoal adsorber canister is a premium, high-capacity filtration unit specifically designed to remove dissolved hydrocarbons and organic compounds from process liquids. Featuring a perforated metal housing with an internal dust-proof liner and factory-prebonded end cap seals, this carbon canister enables operators to replace spent activated carbon quickly and cleanly. This eliminates the handling and disposal challenges associated with bulk activated carbon.

 

Work Principle

 

structural-diagram-of-amine-activated-carbon-filter

The 7NC22 charcoal adsorber canister operates on the principle of adsorption, a surface-based process where contaminants are trapped within the porous structure of activated carbon.

 

  • Flow Path: Contaminated fluid enters the canister from the outside, permeating through the granulated charcoal bed toward the perforated center core. Purified fluid collects in the core and exits through the sealed top outlet.
  • Adsorption vs. Filtration: Unlike mechanical filters that trap particles, activated carbon attracts and holds hydrocarbon molecules, odors, and organic compounds via Van der Waals forces and pore diffusion.
